摘要:


蛋白质剪接是蛋白质内含肽介导的,一种在蛋白质水平上翻译后的加工过程,它由一系列分子内的剪切-连接反应组成。蛋白质内含肽是一个蛋白质前体中的多肽序列,可以催化自身从蛋白质前体中断裂,使两侧的蛋白质外显肽连接成成熟的蛋白质。蛋白质内含肽的发现,不仅丰富了遗传信息翻译后加工的理论,在实践中也有广泛的应用前景。Abstract: Protein splicing , which is an intein mediated posttranslational processing, involves a series of intramolecular cleavage-ligation reactions. Intein is an intervening polypeptide which can catalytic self-cleavage from a pre-protein accompanied by the concomitant joining of the two flanking polypeptides (the extein) through a peptide bond. Protein splicing not only enriches genetic theory of posttranslational processing, but also have wide application prospect.
